The revised Educational Context Perception Questionnaire. Psychometric proprieties [Le proprietà psicometriche del questionario revisionato di percezione del contesto educativo (ECPQ II)]

The revised Educational Context Perception Questionnaire (ECPQ II) is used to assess six dimensions of the students’ classroom perception: cohesion, didactics, mutual appreciation, psychological insecurity with teachers and classmates and discrimination. Bronfenbrenner’s (1979) ecological theory served as a guide for the definition of the research process and the identification of dimensions to explore. The aim of the present study was to analyze the psychometric properties of the ECPQ II. The 26-item version of the ECPQ II was admin-istered to a sample of 1079 students enrolled in upper-secondary schools (9th and 10th grades) in Rome. An Exploratory Factor Analysis (EFA) was applied and the factor model structure was tested for model fit using Confirmatory Factor Analysis (CFA) and Structural Equation Modeling (SEM) on two samples: the full and half random sample. The six-fac-tor model showed a good fit to the data for both samples and had good reliability and factor score determinacy. The current research confirmed the factor structure of the measure and showed that the ECPQ II has supportive psychometric properties of validity and reliability.
